Abstract
[Objective] The new way of the prevention of early wheat seedling being poisoned by Zn2+ stress was explored.[Method] The effect of the salicylic acid(SA) with the different concentrations(10-6,10-5 and 10-4 mol/L) on the physiological characteristics of the wheat seedling as testing material was studied with the method of the water culture containing Zn2+ of 5 mmol/L stress and each treatment with three replications.[Results] The activity of superoxide dismutase(SOD) and peroxidase(POD) in leaf and root of wheat seedling was significantly increased but the content of malondialdehyde(MDA) and the activity of catalase(CAT) in its leaf was increased through the treatment of salicylic acid under Zn2+ stress,which indicated that the SA could induce the resistance of wheat seedling to Zn2+ stress and relief its injury caused by Zn2+ stress.In the treatment of Zn2+ of 5 mmol/L,the effect of the SA of 10-4 mol/L was most obvious.[Conclusion] In the initial period of wheat seedling growth,its activation effect on the antioxidant enzyme under Zn2+stress of it could be arisen and in the latter,it was converted into inhibitory effect.The SA could improve the resistance of wheat seedling to Zn2+ stress and relief its injury caused by Zn2+ stress.
